The zeolitic tuff from Gordes (Western Anatolia) was used as adsorbent for nitric oxide (NO) storage and release purposes The NO loading of the zeolite was performed under 20 mL min(-1) NO flow at 30 C and then the zeolite was purged with inert gas in order to remove the species that were reversibly adsorbed and in the gas phase (desorption) The total and reversible adsorption capacities of the zeolite were determined from the adsorption and desorption breakthrough curves respectively The NO-loaded zeolite exhibited antibacterial and bactericidal activities against Gram-negative (Escherichia colt) and Gram positive b
